Eddie Newman explains how to throw a cast net in to a body of water in order to catch fish. His process is to first put the rope on your right hand attaching it to your wrist, then gather up the rope in your hand, grab the top of the net, then wrap the top of the net around your hand so that you are holding it about a foot down. Then grab the weights and lay them in your fingers, you are now ready to throw. Put the net on your right side and throw, your right hand should cross over your left in an easy motion.
